Drizzledump adding extra ')' to CREATE TABLE output when dealing with foreign keys

[Patrick Crews]

Attempting to use drizzledump to dump a MySQL table with a foreign key like this: (including referenced table so it will be useful)
CREATE TABLE t1(a INT NOT NULL, b INT NOT NULL, PRIMARY KEY(a), KEY b_key1 (b)) ENGINE=Innodb;

CREATE TABLE t2(a INT NOT NULL, b INT , PRIMARY KEY(a), KEY b_key (b),
CONSTRAINT fk_constraint_t2 FOREIGN KEY (b) REFERENCES t1(b) ON DELETE SET NULL ON UPDATE CASCADE) ENGINE=Innodb;

Results in drizzledump output like this:
CREATE TABLE `t2` (
  `a` INT NOT NULL,
  `b` INT DEFAULT NULL,
  PRIMARY KEY (`a`),
  KEY `b_key` (`b`),
  CONSTRAINT `fk_constraint_t2` FOREIGN KEY (`b`) REFERENCES `t1` (`b`) ON DELETE SET NULL ON UPDATE CASCADE
) <--- See this little guy here? He don't belong ; )
) ENGINE='InnoDB' COLLATE='utf8_general_ci';

ok, this is due to an epic regex fail :(
